Thanks for the walkthrough of the previous function - quite nice that it works correctly when there is no previous record. One inconsistency I notice in the formula syntax is that you pass a string to order_by and group_by, rather than passing a reference like $Day, which is how lookupOne and other functions work - is there any reason why a different semantics is used here?
